The objectives of the SUMIT project was to develop, evaluate, and disseminate 20 course modules (microcomputer programs) for instruction in general biology and ecology. To encourage broad utilization, the programs were designed for the Apple II microcomputer and written in Applesoft Basic with a user-adaptable format. Each package focused on a key concept in biology, with specific educational objectives. User's guides documented programs, provided theoretical background, and offered suggestions for modification. Formative evaluation was conducted by project staff, other faculty, and graduate students. In most cases this evaluation was accomplished by pre- and post-testing, using computer administered multiple-choice examinations. For three modules, classes were split and students using computer modules were compared to students using lecture or text-reading instructional formats. In essentially all cases, students filled out a subjective evaluation form dealing with aspects of student preference. Significant short-term learning was found for all modules. The final stage of evaluation was carried out by professional reviewers working under contract with CONDUIT. Although some dissemination of programs occurred during the project, the primary plan for dissemination involves release of the programs to CONDUIT for their review, modification, publication, and marketing.
